Filed: 1985-04-01
Abstract: PURPOSE:To prevent toner from scattering by applying a voltage of necessary polarity to a conductive roller and rubbing the edge part of a seal member in the opposite direction of the rotating direction of the conductive roller. CONSTITUTION:The voltage from a power source 21 is divided by resistors 22 and 23 to a specific value and applied to a sleeve 5, and a bias voltage is applied to a magnetic brush 2 in rotation to attract toner electrostatically on the sleeve 5 as shown by an arrow 27, thereby preventing the toner from sticking on a no-image part on a photosensitive layer 11. Conductive rollers 13 and 14 are applied with a specific voltage to attract toner electrostatically with the voltage as shown by an arrow 28, thereby preventing the toner from scattering. Further, a little toner which is close to a development position and scatters from the surface of the magnetic brush 2 is attracted and gathered as shown by an arrow 29 and returned onto the magnetic brush 2. A photosensitive drum 9 and the conductive roller 13 and 14 are close, so toner never passes through their gap. Consequently, a scatter of toner is inhibited.

Title: Measuring device for current
Inventor: YASUDA KENICHI
IPC: G01R15/22
Filed: 1981-04-30
Abstract: PURPOSE:To insulate a measuring part completely and enable highly precise measurement with ease, by transduing a current to be measured flowing through a current measuring shunt into an optical signal and transmitting the same to the measuring part through an optical fiber. CONSTITUTION:When a current I to be measured flows through a shunt 1, a current IL proportional to the current I flows through a light-emitting diode 2, which delivers an optical signal having the illuminance proportional to the current IL. This optical signal is transmitted to the light-receiving diode 6 of an optical signal receiving part B and transduced therein into a voltage signal proportional to the illuminance. Then, an amplifier 7 removes a voltage corresponding to a base current made to flow through the light-emitting diode 2 by supplying a bias voltage, and supplies a voltage signal proportional to the current to be measured to a measuring part 8. By this constitution, a current in a high- voltage part can be measured without being restricted by an insulation level and, in addition, the effect of noises can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To approximately uniformly consume a TiB2 target and to evaporate TiB2 stably for a long time by using a constant voltage arc ion plating device and evaporating TiB2 from a TiB2 target by pulse discharge. SOLUTION: A constant voltage arc ion plating device is used, discharge in which current value is low suppressed is started by a constant voltage power source 8, and the main discharge is generated by a constant voltage power source 9. As to the constant voltage power source 9, pulse voltage is adopted, and the discharge is intermittently generated.

Therefore, the places to be discharged are completely at random and are not confinded to one place, erosion on the same place does not occur, and TiB2 can be evaporated for a long time.

Title: Rom driving circuit
Inventor: MORI TOSHIFUMI
IPC: G11C17/12
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To make increasable the ROM operation margin by lengthening a ROMTr forming period to solve such a problem that read-out in ROM operation may be failed and ROM operation margin may not be given during a ROMTr forming period, namely margin is not given at a 'High' level of a pre-charge signal in a ROM driving circuit. SOLUTION: The number of stages of a N-MOS transistor 21 is made more than the number of stages of a N-MOSTy 31 of a MainROM 13. Thereby after pre-charge of the MainROM 13 is finished, pre-charge of the N-MOSTr 21 of the gate circuit 14 is finished later (pre-charge signal 43 is at 'High' level), and thus, the ROM operation margin is increased by lengthening the ROMTr forming period.

Title: Compact disk player
Inventor: HAGINO YUKIHIKO
IPC: G11B7/09
Filed: 1983-04-15
Abstract: PURPOSE:To obtain high resistance to vibration by detecting the actual vibration by a vibration pickup and discriminating the vibration levels to set a proper amplification degree for a servo circuit. CONSTITUTION:The actual vibration is detected by a vibration pickup 16 and then amplified by an amplifier 17 together with conversion of impedance. The output signal of the amplifier 17 corresponding to the acceleration of vibration is supplied to an identification circuit 18. Then a voltage level corresponding to an optional acceleration of vibration is set to obtain a 2-step output. This 2- step output signal is applied to servo amplifiers 19 and 20 having variable amplification degrees. Thus the large and small amplification degrees are obtained from the large and small vibrations, respectively. In other words, the vibration resistance is satisfactorily improved to a large vibration in both focus state and tracking state. At the same time, the generation of noises is suppressed with a small vibration.

Title: Crescent lock with stopper
Inventor: TAIRA TOSHINORI
IPC: E05B37/16
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To simply open and operate no stopper even in the case where a window glass or the like broken by an illegal invader by hooking the stopper closed in a position locking a crescent piece to switching operation impossibility by a push button lock mechanism. SOLUTION: The locking ring 25 of a reset state engages a projection part 23' with the contact part 16 of a stopper 7 to maintain the stopper 7 at a closed set position. Since for the first time the contact part 16 is released by the push operation of the push button 10 of the prescribed number of times set in a push button lock mechanism 9, unlocking can be not performed by a person who does not know a code number. Thus, since the unlocking operation of a crescent lock by an invader is made nearly impossible, he can be blocked from further invasion, and locking reliability of the crescent lock and theft prevention effect can be enhanced further.
